Finescale standards or Fine Standards are

model railway Railway modelling (UK, Australia, New Zealand, and Ireland) or model railroading (US and Canada) is a hobby in which rail transport systems are modelled at a reduced scale. The scale models include locomotives, rolling stock, streetcars, t ...

standards that aim to be close to the prototype dimensions. Reduction in toylike, overscale flanges, pointwork, etc. In Britain it is particularly used because small British prototypes meant that track gauge is underscale. Modelling to finescale standards requires skill, so modellers usually start with the coarse standards applied to ready-to-run models suitable as toys. Standards are set by modellers' societies.

4 mm scale 4 mm scale is the most popular model railway scale used in the United Kingdom. The term refers to the use of 4 millimeters on the model equating to a distance of 1 foot (305 mm) on the prototype (1:76.2). It is also used for military m ...

3 mm finescale 3 mm scale, also known as 3 mm finescale, is a model railway scale of 3 mm: 1 ft used for British prototypes. Introduced as British TT gauge, it sits approximately halfway between British N gauge and OO gauge, but is not as po ...

2 mm finescale 2 mm scale, often 2 mm finescale is a specification used for railway modelling, largely for modelling British railway prototypes. It uses a scale of 2 mm on the model to 1 foot on the prototype, which scales out to 1:152. The t ...
